ACPL-K24L-000E

Low Power 5MBd Digital Optocoupler

Overview

The Broadcom ACPL-K24L is a dual-channel stretched SO-8 package version of the compact ACPL-x2xL 5MBd digital optocoupler product family. The device features high-performance LED and detector IC design. The detector has a CMOS output stage and an optical receiver input stage with built-in Schmitt triggers to provide logic-compatible waveforms, eliminating the need for additional waveshaping. The ACPL-K24L is extremely low power performing at maximum 1.1mA IDD current per channel across industrial temperature range. With a forward LED current as low as 1.6 mA, most microprocessors (MCUs) can directly drive the LED.

An internal shield on the ACPL-K24L guarantees common mode transient immunity of 25 kV/µs at a common mode voltage of 1000 V over a temperature range of -40°C to +105°C. The device has glitch-free output upon system power-up and power-down.

Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials within an electrical system. Such systems must be able to operate reliably for many years when used in industrial, medical, renewable energy environments, and any other system that has a long expected operating lifetime.

The ACPL-x2xL digital optocouplers are designed for various applications such as computer peripheral interfaces, microprocessors system interfaces, high speed line receiver, power control system and more.
